NSFW is a strange frase in my opinion. Not save for work means boss could get mad.
There are many instances where one can/must use nude to accomplish wanted effect.
For me there is a huge difference betweeen a nipple and hardcore porn.
Although I understand the site regulations concerning NSFW, I feel we have to bow for an group of prude people, often instigated by religion.
If You know that the biggest porn industry is in the USA, and in that same country people get offended by the Venus of Milo due to nudity, One must conclude that this whole NSFW thing is hypocoristic to the max.
Shame we all abait by these " no nudes" demands.
If it were up to me, one could show a full monty in the gallerie
